Hiring the wrong grant writing service can waste months and thousands of dollars on proposals that never get funded. Before you commit, you need to ask the right questions to separate experienced, results-driven providers from those just collecting fees. Here's what to vet before signing a contract.
Do They Have Proven Success in Your Funding Area?
Grant writing isn't one-size-fits-all. A firm that excels at federal STEM grants might flounder with foundation proposals for arts nonprofits. Ask potential providers for specific examples of funded grants they've written—not just general case studies. Request the actual grant amount, funder name, and organization type.
Look for concrete success rates. A reputable service should tell you what percentage of their proposals get funded, ideally broken down by grant type (federal, foundation, corporate). If they won't share this, that's a red flag. Industry benchmark is roughly 30-50% for federal grants and 40-60% for foundation grants, depending on competitiveness.
What's Their Fee Structure and Timeline?
Grant writing fees vary wildly. Hourly rates typically range from $75-$250 per hour, while project-based fees for a single grant proposal run $2,000-$10,000+. Some providers work on contingency (taking a percentage of awarded funds, usually 5-15%), though this can create conflicts of interest.
Ask about the timeline upfront. Most grants require 4-8 weeks of development time before submission. If a provider promises results in two weeks, they're cutting corners. Clarify whether their fee covers revisions, resubmissions if rejected, or only the initial proposal.
Do They Understand Your Organization's Mission?
A good grant writer will spend time learning your nonprofit's strategy, financials, and donor relationships before writing anything. Ask how many discovery meetings they schedule with new clients. Expect at least 2-3 hours of initial consultation.
Request their process for understanding your funding gaps and organizational capacity. They should ask tough questions about your board, staff expertise, and ability to manage new funding. A provider who jumps straight to writing without vetting feasibility is selling you false hope.
Who Will Actually Do the Writing?
Many grant writing agencies have tiered staff. The senior strategist pitches your account, but a junior writer does the actual work. Ask who will be your primary contact and who writes your proposals. If it's a one-person operation, clarify their bandwidth and backup plan.
Also ask about their team's credentials. Look for writers with:
- Grant management experience (not just writing)
- Subject-matter expertise relevant to your field
- Training in current funder priorities (foundations and government agencies update guidelines yearly)
- Professional certifications like the Certified Grant Writer (CGW) credential
Will They Provide a Needs Assessment or Strategy First?
The best grant writers start with a funding strategy session, not a proposal draft. This involves mapping your funding needs, identifying aligned funders, and creating a multi-year funding roadmap. Some charge separately for this ($1,500-$3,500); others include it in project fees.
Ask whether they'll conduct a competitive analysis of similar organizations and their funding sources. This helps position your proposal to stand out. If they skip this step, they're writing blind.
How Do They Stay Current on Funder Preferences?
Funding landscapes shift. Foundations deprioritize areas, government agencies release new strategic plans, and corporate giving focuses change. Ask how the provider monitors these shifts and applies them to your proposals.
A solid answer includes subscriptions to funder research databases (like Foundation Center or Grants.gov notifications), attendance at grant writing conferences, and relationships with foundation program officers. If they can't explain this, they're operating with outdated knowledge.
Can They Provide References from Similar Organizations?
Request at least three references from nonprofits similar in size and mission to yours. Call them directly and ask:
- Did proposals get funded?
- Was communication responsive?
- Did the provider adapt to feedback?
- Would they hire again?
If a provider won't give references, move on.

Frequently Asked Questions
Q: How much should I expect to pay for a competitive federal grant proposal? Most established grant writers charge $3,000-$7,000 per federal proposal, reflecting the complexity and compliance requirements involved.
Q: Can a grant writing service guarantee funding? No legitimate provider will guarantee funding; grants are awarded by independent decision-makers, not the writer.
Q: Should I hire one provider for all grant types or use specialists? Specialists in your sector (federal vs. foundation, specific fields) typically deliver better results, though a generalist familiar with your mission can manage your overall strategy.
